A New Concept in Ubiquitous Network Management: Guest Node Monitoring--Applications of the MobileIPv6-MIB--

To keep pace with the recent growth of mobile and ubiquitous networking environment, new technologies in network management need to be explored. MobileIPv6-MIB has been proposed at the IETF as a core technology for effective management of mobile and ubiquitous networks based on MobileIPv6 technology. In this paper we explain the functionalities of MobileIPv6-MIB, and discuss a new concept in ubiquitous network management viz. "Guest Node Monitoring" that significantly expands the scope and reach of network management. We focus on the problem of monitoring guest nodes attached to a management domain. It is difficult for the local network manager to monitor such nodes directly. We propose a novel model for guest node monitoring based on MobileIPv6-MIB. We have implemented the prototype system of our model, and conducted experiments on how the system works.
